>>12696783In order for the universal speed limit to be finite objects must have an alternate experience of time when at velocity/position/gravitational stress-energy tensor differences to one another.
Every particle has it's own worldline in 4d space but the worldlines can be separately transformed in counter-intuitive ways
The alternative, where the speed limit is infinite, has significant failures with the transmission of motion from one particle to another inside macroscopic objects. Several interesting momentum based paradoxes arrive when we try to combine molecular theory and newtonian physics, to say nothing of the optical paradoxes
